Protein Inhalation Powders: Spray Drying vs Spray Freeze Drying

Pharmaceutical Research, 1999
To develop a new technique, spray freeze drying, for preparing protein aerosol powders. Also, to compare the spray freeze-dried powders with spray-dried powders in terms of physical properties and aerosol performance.Protein powders were characterized using particle size analysis, thermogravimetric analysis, scanning electron microscopy, X-ray powder ...

Dry Powder Aerosols I: A New Powder Inhalation Device

Journal of Pharmaceutical Sciences, 1971
Abstract A new portable device is described for administration of powdered drugs by inhalation. Powder contained in a standard hard gelatin capsule is induced to flow from the capsule into the air stream by a vibratory feed mechanism arising from a rotor driven by the inhaled air.

Spray freeze drying for dry powder inhalation of nanoparticles

European Journal of Pharmaceutics and Biopharmaceutics, 2014
Formulating nanoparticles for delivery to the deep lung is complex and many techniques fail in terms of nanoparticle stability. Spray freeze drying (SFD) is suggested here for the production of inhalable nanocomposite microcarriers (NCM). Different nanostructures were prepared and characterized including polymeric and lipid nanoparticles.

Inhalation Performance Analysis of Dry Powder Inhaler

International Journal of Pharmaceuticals, Nutraceuticals and Cosmetic Science
Dry powder inhalers (DPIs) are commonly used to treat respiratory diseases, particularly asthma, lung cancer, and chronic obstructive pulmonary disease, by delivering medications directly to the lungs. This review explores the influence of key formulation parameters such as particle size, morphology, surface roughness, and excipients on the inhalation ...

[Easyhaler--ideal dry powder inhaler].

Polski merkuriusz lekarski : organ Polskiego Towarzystwa Lekarskiego, 2010
Dry powder inhalers (DPI) differ among each other in many technical aspects, size and value of lung deposition as well as clinical efficacy of inhaled drugs. Easyhaler is a reservoir, multi-dose, high-resistance DPI and it is easy to operate. The device needs low inspiratory flows which are possible to achieve even by asthmatic children over 5-year-old

Dry Powder Inhalers (DPI): A Comprehensive Review Article on Dry Powder Inhaler (DPI)

In the treatment of respiratory conditions like asthma and chronic obstructive pulmonary disease (COPD), dry powder inhalers (DPIs) have emerged as a crucial substitute for pressurized metered-dose inhalers (pMDIs). The desire for more effective and user-friendly drug delivery systems, as well as environmental concerns about the chlorofluorocarbon (CFC)
